I put a red comb tail gourami in my community tank and when I got off work my black molly was screwed up bad. his top fin is like non exhistant and his tail fin is shredded. will the fins grow back? Is there something I can do to help it heal? I removed the combtail from the tank. actual name of the fish is ceylon combtail. some of my other mollies got the crap ripped outta them too but the black one is the worst. please let me know if the fins will heal/grow back.

i would add melafix to the water per instruction on bottle,
keep the water as clean as possible,with regualr water changes,
the fins should grow back,are you taking the combtail back to the store ?http://peteducation.com/article.cfm?...+1957&aid=2568
i found this,if it's any help.

Yes, in time they will grow back. One of my otos got stuck in a spinach clip as I was removing it. It took off nearly his entire tail!
It took awhile but he now has a nice new tail. This incident taught me to carefully look at (and in) the clip before removing it.
